Should Toronto build affordable housing over public facilities? We chatted live on Tuesday, March 18 at 1 p.m. EST.

Our experts: David Oleson, an architect and principal of Oleson Worland Architects, established in Toronto in 1984, and Alan Littlewood, a Toronto architect who has been practising architecture for 40 years, mainly in the areas of housing and urban design. Star urban affairs columnist Christopher Hume will moderate.

We invite the experts every Tuesday at 1 p.m. EST to discuss a range of Big Ideas that are making our city buzz.
